Current understanding of aspen fire ecology in western North America includes the paradoxical characterization that aspen-dominated stands, although often regenerated following fire, are “fire-proof”. We tested this idea by predicting potential fire behavior across a gradient of aspen dominance in northern Utah using the Forest Vegetation Simulator and the Fire and Fuels Extension. The wind spe...

Although fire is inherently dangerous, leading many animals to avoid it, for most of human history, mastery of fire has been critical to survival. Humans can therefore be expected to possess evolved psychological mechanisms dedicated to controlling fire. Because techniques for starting, maintaining, and using fire differ across ecosystems, the postulated adaptations can be expected to take the ...

Forest fire evolution plays an important role in the decision-making of controlling the forest fire. This paper aims to simulate the dynamics of the forest fire spread using a cellular automaton approach. Having analyzed the characteristics and evolution of forest fires, a simulation model for the forest fire evolution based on the energy accumulation and release is proposed. And, taking Austra...

The time between when a fire crew is dispatched to a fire and when it arrives is an important factor in determining the size of a forest-fire and the resources required to put the fire out. Traditionally, travel time has been looked at as a point-to-point network problem. In this case, travel (by vehicle and by foot) may start and end at an infinite number of locations across the landscape. A r...

Fire is one of the incorporate vegetation management practices for grasslands and semi-arid rangelands. It may affect symbiotic relationship between range plants and mycorrhiza. Accordingly, this research was aimed to investigate the effects of a spring prescribed fire on the symbiotic relationships between mycorrhiza and 6 plant species. The study was conducted in a semi-arid steppe rangeland ...

Accurate near real time fire emissions estimates are required for air quality forecasts. To date, most approaches are based on satellite-derived estimates of fire radiative power (FRP), which can be converted to fire radiative energy (FRE) which is directly related to fire emissions. Uncertainties in these FRE estimates are often substantial. This is for a large part because the most often used...

In the past, HSE’s Health and Safety Laboratory (HSL) has studied the performance of a variety of passive fire protection (PFP) materials in protecting a part-filled LPG tank subjected to hydrocarbon pool fire engulfment. However, this is only one potential fire incident scenario that can threaten a process vessel; another is a jet fire, perhaps resulting from an ignited release from a leaking ...

Remotely sensed infrared images are often used to assess wildland fire conditions. Separately, fire propagation models are in use to forecast future conditions. In the Dynamic Data Driven Application System (DDDAS) concept, the fire propagation model will react to the image data, which should produce more accurate predictions of fire propagation. In this study we describe a series of image proc...
